Film cartridge opening device

ABSTRACT

A FILM CARTRIDGE OPENING DEVICE FOR FILM CARTRIDGE OF THE TYPE HAVING A SUPPLY CHAMBER, A TAKE-UP CHAMBER, AND A BOX-LIKE EXPOSURE PLATFORM RIGIDLY INTERCONNECTING THE CHAMBERS. THE TAKE-UP CHAMBER OF A CARTRIDGE IS MOUNTED ON A SPINDLE, AND THE CARTIDGE ROTATED ON THE SPINDLE UNTIL THE EXPOSURE PLATFORM IS MOVED ONTO A FIXED DETECTOR HEAD. THE DETECTOR HEAD HAS FLUIDIC PORTS FOR SENSING NOTCHES IN THE EXPOSURE PLATFORM INDICATING THE TYPE OF FILM CONTAINED IN THE CARTRIDGE. THE DETECTING SYSTEM IS PRESENT TO SENSE A PREDETERMINED TYPE OF CARTRIDGE AND FILM, AND IF SUCH CARTRIDGE IS SENSED, THE CARTRIDGE BREAKING MECHANISM WILL OPERATE, WHEN ACTUATED, TO BREAK THE CARTRIDGE AND PERMIT REMOVAL OF THE FILM THEREFROM. IF A CARTRIDGE CONTAINING A DIFFERENT TYPE OF FILM IS SENSED BY THE DETECTING SYSTEM, THE CARTRIDGE BREAKING MECHANISM   WILL NOT OPERATE, IF ACTUATED, AND A SINGLE DEVICE WILL BE ACTUATED. THE BREAKING OF THE CARTRIDGE IS ACHIEVED BY A BREAKING RAM WHICH ENGAGES AND URGES THE SUPPLY CHAMBER OF THE CARTRIDGE IN A DIRECTION SUBSTANTIALLY PARALLEL TO THE SPINDLE AXIS FOR BREAKING THE SUPPLY CHAMBER, MOST OF THE EXPOSURE PLATFORM, AND THE TAKE-UP CHAMBER CAP AWAY FROM THE TAKE-UP CHAMBER AND THE FILM SPOOL, WHICH REMAINS ON THE SPINDLE. ACCORDINGLY, SUBSTANIALLY THE ENTIRE LOWER AND OUTER SIDES OF THE TAKE-UP CHAMBER ARE OPEN FOR THE WITHDRAWAL OF FILM FROM THE SPOOL.

Cl. 326i 3/00 U.S. Cl. 225103 2 Sheets Drawing. 16 Pages Specification A film cartridge opening device for film cartridges of the type having a supply chamber, a take-up chamber, and a box-like exposure platform rigidly interconnecting the chambers. The take-up chamber of a cartridge is mounted on a spindle, and the cartridge rotated on the spindle until the exposure platform is moved onto a fixed detector head. The detector head has fiuidic ports for sensing notches in the exposure platform indicating the type of film contained in the cartridge. The detecting system is preset to sense a predetermined type of cartridge and film, and if such cartridge is sensed, the cartridge breaking mechanism will operate, when actuated, to break the cartridge and permit removal of the film therefrom. If a cartridge containing a different type of film is sensed by the detecting system, the cartridge breaking mechanism will not operate, if actuated, and a signal device will be actuated. The breaking of the cartridge is achieved by a breaking ram which engages and urges the supply chamber of the cartridge in a direction substantially parallel to the spindle axis for breaking the supply chamber, most of the exposure platform, and the take-up chamber cap away from the take-up chamber and film spool, which remains on the spindle. Accordingly, substantially the entire lower and outer sides of the take-up chamber are open for the withdrawal of film from the spool.
